How to Choose Saw Blades?

Briefly, here's how to choose a saw blade.

The blade's weld appearance, the area where the alloy connects with the blade body, should not be too yellow like copper. There should be no cold joints or missed welds. The solder should have a slightly white appearance, a thin line. It should be very clean and tidy. There should be no green copper rust.

This is related to safety; no one wants a piece of alloy blade flying out while cutting wood, with the power equivalent to a small caliber rifle.

2. A quality saw blade is precision ground on all four sides: both sides, the front tooth surface, and the top. The grinding is even and smooth, with no irregularities, excellent consistency, and sharp blade edges. The surface is bright and free of any missed or unground areas. Additionally, the blade is designed with a front higher than the back, as a lower back edge can gum up wood.
